In addition to the species ennmoratod above, tlie Collection 

 contains two further species of this <rroup (a male and two 

 females of one and two pairs of the other), which 1 believe 

 to be new and describe below. 



The species (?. oodioides, C\id.= Oodes punaticoU'is, I'oh., 

 is quite unknown to me as well as to Dr. Wringuey, who 

 states in reference to it that the type is no longer in the 

 Stockholm Museum. It is very probable that it is not a 

 Chhcnius at all, but a Systolocranius, which, if it is truly 

 referable to Boheraan's Oodes pwicticoUis (page 161, Ins. 

 Cati'rariie), the description certainly suggests it to be. 



To assist in the determination of the new with the pre- 

 viously described species of the group, the following brief 

 table may be useful : — 



1 (10). Colour black ; legs, palpi, and 



antennas wholly reddish. 



2 (7). Legs and auteunaj longer, the 



latter tiliform. 

 o (4). Size I25-I3 mm.; sexes alike; 

 prothornx tra])eziform, hardly 

 sinuate laterally, densely punc- 

 tate ; puncturatiou beueath

 opaque, intervals nearly plane, 

 shagreen-punctate C. pkeus, Chaudoir. 



4 (p>). Size smaller (10-11 mm.); males 



shiny ; females — elytra sub- 

 opaque ; protliorax naiTOwer, 

 more sinuate laterally above 

 posterior angle ; puucturation 

 beneath coarser and more dis- 

 tributed C. simulatorms, sp. n. 



5 (3). Size similar ; prothorax straight 



laterally, smooth, very shiny, 

 more or less sparsely punctated 

 about base and sides ; elytra
